SUMMER 2007

This report provides water quality test results for samplesdrawn during 2011 and from required historical test results.Once again, the test results show your drinking water is of ahigher quality than state and federal standards require.In addition to detailed results of water quality testing, this

report also contains a description of local water sources, an-swers to common questions about water quality, and infor-mation to help your family or business conserve the preciouswater resources of our community.

waternewsWe Passed Our Annual Water Quality Checkup

Water Quality RegulationsIn order to ensure that tap water issafe to drink, the U.S. EnvironmentalProtection Agency (USEPA) and theState Department of Health Servicesprescribe regulations that limit theamount of certain contaminants inwater provided by public water systems.Food and Drug Administration (FDA)regulations establish limits forcontaminants in bottled water thatmust provide the same protectionfor public health. For informationgo to www.epa.gov.

Quality Water SupplyYour drinking water comes from localgroundwater supplies.

Your Water Is Highly TreatedWe operate four advanced water treatment facilities to produce safe, high-quality water.

We Test for QualityOur state-certified water quality professionals monitor your water 24 hours a day, 7 days a week, to ensurethe safety of your water.

Frequency of Tests: Some tests are donedaily, others weekly, monthly, or at other in-tervals. Some measurements are takencontinuously, around the clock, using so-phisticated equipment. We do more testing than required by state and federalregulators.

Certified Labs: Tests and results are produced by independent state-certified fa-cilities.

Test Accuracy: The thousands of tests we conduct every year are done with ex-traordinary accuracy. Many substancescan be detected at a level of two gramsper one million gallons of water.

Our Commitment to Providing Quality Water

When to Seek Health Care Advice

Our water supply is from undergroundaquifers that are less susceptible

to surface water contaminants. Somepeople may be more vulnerable to contaminants in drinking water thanthe general population. Immuno-compromised persons such aspersons with cancer who are undergoingchemotherapy, persons who have undergone organ transplants, people withHIV/AIDS or other immune-systemdisorders, some elderly, and infants canbe particularly at risk from infections.These people should seek advice aboutdrinking water from their health careproviders. EPA/Centers for DiseaseControl (CDC) guidelines on appropriatemeans to lessen the risk of infection byCryptosporidium and other microbialcontaminants are available by callingthe Safe Drinking Water Hotline at 1-800-426-4791.

Water in the EnvironmentSources of drinking water (both tap water and bottled water) include rivers, lakes,

streams, ponds, reservoirs, springs, and wells. The District’s current source of supplyis 100 percent groundwater. As water travels over the surface of the land or throughthe ground, it dissolves naturally occurring minerals and, in some cases, radioactivematerial, and can pick up substances resulting from the presence of animals or fromhuman activity. Contaminants that may be present in source water include:

Microbial contaminants, such as viruses and bacteria, that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

Inorganic contaminants, such as salts and metals, that can be naturally occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.

Pesticides and herbicides, that may come from a variety of sources such as agriculture,urban storm water runoff, and residential uses.

Organic chemical contaminants, including synthetic and volatile organic chemicals, thatare by-products of industrial processes and petroleum production and can also comefrom gas stations, urban storm water runoff, agricultural applications, and septic systems.

Radioactive contaminants, that can be naturally occurring or the result of oil and gas production and mining activities.

An assessment of the drinking water sources for the Scotts Valley Water District wascompleted in September 2001 and January 2011. The sources are considered most vul-nerable to the following activities associated with contaminants detected in the watersupply: drycleaning, gasoline storage and distribution, and manufacturing. In addition,the sources are considered most vulnerable to these activities: abandoned water andmonitoring wells, septic systems, transportation corridors, commercial parking lots,and sewer collection systems. A copy of the complete assessment is available at the District Office at 2 Civic Center Drive, Scotts Valley or by e-mail at contact@svwd.org.

Where to Get More InformationDrinking water, including bottled water, may reasonably be expected to contain at least smallamounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by callingthe EPA’s Safe Drinking Water Hotline at 1-800-426-4791.

The tables below list all of the drinking water contaminants and other constituents detected between January 1 and December 31, 2011. Secondary Standards in the table refer to aesthetic aspects of water. Ingeneral, water quality remained constant or improved in 2011 and meets all State and Federal standards.

CONTAMINANT MCL or MRDL PHG or MCLG RANGE AVERAGE SOURCE OF CONTAMINATION

DEFINITIONS USED IN THIS CHART:

Grains per Gallon: A unit of hardness where17.1 parts per million equals 1 grain per gallon.

Turbidity: A physical characteristic of water thatmakes the water appear cloudy. The condition is caused by the presence of suspended matter.We monitor it because it is a good indicator ofthe effectiveness of our filtration system.

Langelier Index: This index is used in stabilizingwater to control both corrosion and the deposition of scale.

MCLG: Maximum Contaminant Level Goal: Thelevel of a contaminant in drinking water belowwhich there is no known or expected risk tohealth. MCLGs are set by the U.S. EnvironmentalProtection Agency.

MCL: Maximum Contaminant Level: The highestlevel of a contaminant that is allowed in drinkingwater. Primary MCLs are set as close to thePHGs or MCLGs as is economically and technologically feasible. Secondary MCLs areset to protect the odor, taste, and appearance of drinking water.

Micromhos per Centimeter: An indicator of dissolved minerals in the water.

MRDL: Maximum Residual Disinfectant Level.The highest level of a disinfectant allowed indrinking water. There is convincing evidencethat addition of a disinfectant is necessary forcontrol of microbial contaminants.

NA: Not applicable.ND: Not detected at testing limit. NTU: Nephelometric turbidity unit, indicating the clarity of the water.pCi/L: Picocuries per liter is a measure of radioactivity.PDWS: Primary Drinking Water Standards: MCLs and MRDLs for contaminants that affecthealth along with their monitoring and reportingrequirements, and water treatment requirements.PPB: Parts per billion or micrograms per liter. 1 PPB equals 0.001 PPM and is equivalent toabout one drop in 17,000 gallons of water.PPM: Parts per million or milligrams per liter. 1 PPM equals 1,000 PPB and is equivalent toabout one drop in 17 gallons of water.PHG: Public Health Goal: The level of a contaminant in drinking water below which there is no known or expected risk to health.PHGs are set by the California EnvironmentalProtection Agency.Total Dissolved Solids: An indicator of dissolvedminerals in the water.TON: Threshold Odor Number: The unit of odor.

90TH Percentile: The third highest sample resultof 20 sample results.

B. Our treatment plants remove a combination of iron, manganese, arsenic, sulfide, and reduced constituents inherent to the Scotts Valley groundwater supply. Where needed volatile organic compounds are also removed.

C. The State allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently.
